CAUTION

R I S K￿￿O F￿￿E L E C T R I C￿￿S H O C K

WARNING: to prevent fire or shock hazard, doDnotO￿￿N O Texpose￿￿O P E N this unit to rain or moisture. Care should be taken to prevent objects or liquid from entering the enclosure. Never handle the power cord with wet hands.• The lightning flash with arrowhead within a triangle is intended to alert the user of the presence of

uninsulated "dangerous voltage" within the product's enclosure that may constitute a risk of electric shock to you.

• The exclamation point within a triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the unit.

• Caution: To prevent the risk of electric shock, do not remove cover. No user-serviceable parts inside. Refer servicing to qualified service personnel.

• If an outdoor antenna is installed, be sure it is grounded to provide some protection against voltage surges and built up static charges. Keep outdoor antennas away from power lines.

• Unplug the receiver from the AC outlet when plugging in or unplugging cables, when left unused for an extended period of time, when moving the receiver, or when you suspect lightning in your area.

• Prevent damage to the power cord. Replace the power cord if it becomes damaged in any way. Always grasp the plug on the power cord when plugging or unplugging the receiver from the AC outlet.

• Your system may produce sound levels capable of causing permanent hearing loss. Do not operate for extended periods of time at high volume levels.

• Protect the receiver from impact and place the receiver on a level surface.

• The receiver is equipped with raised feet to provide ventilation, reduce acoustic feedback, and pro- tect against scratching the surface the unit is resting on. B&K advises against removing the feet.

• Do not stack anything on top of the receiver (processor, source, etc.) Leave a minimum of 3" clear- ance from the top of the receiver to the next shelf (or component).

• The receiver should be located away from sources sensitive to heat.

• Do not perform any internal modifications to the receiver.

• Always connect the receiver's power cord to a dedicated AC outlet for normal operation.

• It is recommended that the system speaker impedance seen by the amplifier channels of the receiv- er not fall below 4 ohms. Best amplifier thermal stability is achieved when the it operates into a 4 ohms or greater speaker load. The nominal impedance of most home speakers range between 4 and 8 ohms. Two 8 ohm speakers in parallel is equal to a 4 ohm (system impedance).

• If young children are present, adult supervision should be provided until the children are capable of following all rules for safe operation.

• Mistaking CONTROL OUTPUT or IR INPUT connectors for audio/video inputs or outputs may dam- age your receiver or other components.

The receiver should be serviced by qualified personnel when:

A. The receiver is not functioning properly.

B. Objects have entered the chassis.

C. The receiver was exposed to rain or any other type of moisture.

D. The receiver was dropped, or the chassis is damaged.
